"Windows 8 build 7850.0.winmain_win8m1.100922-1508 contains a number of references to a brand new feature in Windows: Portable Workspaces. Microsoft will allow Enterprise customers to create USB storage driven copies of Windows. 'Portable Workspace is a Windows feature that allows you to run Windows from a USB storage device', notes Microsoft in its description of the feature inside Windows 8." So, yeah, something we've been waiting for in Windows since, well, forever. Also, push notifications, a screenshot tool and a new webcam application have been discovered as well.

Well, aren't ms being revolutionary now? I mean, nobody else has ever had support for running the entire os off of a USB drive, have they? What awesome features will they come up with next? Standard bluetooth drivers so we no longer have to muck about with manufacturer-specific crap? Keep them coming, Microsoft. The world is hanging on your every move.
All sarcasm aside, I like Windows 7 for the most part. There are, however, several areas where Windows just feels antiquated as compared to other oses. USB booting support is one of them, lack of standard bluetooth drivers is another.
